Abusing Windows Management Instrumentation (WMI) to Build a Persistent Asynchronous and Fileless Backdoor. Imagine a technology that is built into every Windows operating system going back to Windows 95, runs as System, executes arbitrary code, persists across reboots, and does not drop a single file to disk.

Artificial Gravity Atomic Rockets projectrho

Currently, science knows of precious few methods of simulating gravity on a spacecraft.. These boil down to using acceleration by thrusting the ship, spinning the ship (or sections of the ship) to utilize "centrifugal force", or placing a large mass under the ship (generally by landing on a planet).. Centrifugal force is the method of choice for obvious reasons.

Separating Bulk Solids Precision Screening Density

The chemical process industries (CPI) have many applications that require classifying or separating solid materials. Examples of separation or classification processes include those operations that attempt to isolate specific material fractions according to particle size, scalp off the coarse fraction of a material stream, de dust the fine fraction of a material stream or remove the
